The Speed thing shows as 0.5 speed (this is the speed of the CPU upscaling while the normal full GPU shows it as 1x speed

noted last night in the testing for an unknown reason when using the CPU encoding it breaks the speed

I tried many times. But I cannot upscale. Can you fix it, please?

i have a 1060 and while with CUDA I can do 1:1 speeds the use of NVENC takes a 200mb into a 30mb low bitrate mess with the Low compression and while I can turn off Hardware A, it takes twice as long to upscale so is there a way to use CUDA to upscale but CPU to encode

Can we get an option in the GUI to choose the quality ourselves? What I mean to say is let's say I don't want to use the built-in quality parameters in the GUI and I want to use ffmpeg's crf 0 or crf 52 or whatever, we should be able to do that, maybe perhaps we can also get a input box in the GUI where we can also pass on additional FFmpeg CLI parameters?

Thank you!

Would like an option to burn in subs from mkv file when outputting to mp4 should be feasible if ffmpeg is used under the hood?

Hi Mikigal,

I've done some testing and it looks like there are issue with processing anime with .ass subtitles and .ttf attachments.

I've used the same video file but removed the .ass subtitle and .ttf attachments it appears to covert without issue even if there are still attachment to the .MKV container.

See the log below.

Hi. thank you for this great tool. I have some video that not in 4:3 nor 16:9. How can I keep its aspect ratio/prevent stretch?

I don't really have much of a clue what's wrong. I don't. When I upload another version of ffmpeg, I get another error

I think there is a problem when upscaling, causing the video to not be as good as when upscaling using mpv with anime4k shaders (it might even be worse than the original video tbh). Also, it doesn't seem like the compression is doing well(on a 46 000KB file there is only a difference of 5000KB between low and high settings, and even on the low one we lose 40KB of data).
